Abstract

Complexes of lanthanides with N,N′-bis(2-hydroxybenzylidene)-2-hydroxyphenylmethanediamine (H3L) were synthesized and investigated by the elemental, IR, magnetochemical, and thermogravimetric methods. Using the data obtained, they were found to have compositions Ln2L2 · NH2O and La2L2 · MCl2 · 4H2O (Ln = La3+, Pr3+, Nd3+, Dy3+, Er3+; M = Cu2+, Co2+, Ni2+; N = 4, 6). Suggestions on their structures were made. In the interval of 20–140°C, these complexes were shown to be high-resistance semiconductors.
